Sec. 110-57. Inspections, sampling and testing requirements.

Inspection and sampling and testing requirements shall be as follows:

(1) Inspections:

a. The following three types of inspections will be made during the progress of the project:

1. Intermediate progress inspections which can be made at any time.

2. Phase inspections which are required at the completion of a major phase of work and prior to the start of the next phase of work.

3. Final acceptance inspection which will be made upon the completion of all work.

b. All inspections will be made by the planning and community development director or his/her designated representative. The phase inspections and the final inspection will be made with the contractor and the engineer.

c. The planning and community development director or his/her designated representative has the authority to increase the amount of inspection and/or testing. Intermediate progress inspections are required on pipe underdrains before the granular backfill material is placed above the top of the pipe.

d. A phase inspection is required upon the completion of the following phases of work:

1. Subgrade.

2. Base course and curb and gutter.

3. Paving.

e. Any work performed on a phase prior to the approval of the previous phase shall be removed and replaced with satisfactory materials and workmanship.

f. All unsatisfactory work or materials shall be removed and replaced with satisfactory materials and workmanship.

g. If the project is long, the phase inspections may be made on a small portion of the project, but not less than 1,000 feet in length.

h. The engineer is responsible for contacting the planning and community development director or his/her designated representative at least 24 hours prior to the need of a major phase inspection.

i. The engineer will accompany the planning and community development director or his/her designated representative on all inspections.

(2) Testing:

a. The city shall retain the services of a testing laboratory or registered professional engineer practicing in the materials and testing field (hereafter referred to as the lab engineer) to perform all sampling and testing. The developer will reimburse the city for the costs of all sampling and testing performed on the project, including any additional sampling and testing as a result of failing tests and/or poor workmanship before the street will be accepted by the city.

b. The lab engineer will report all test results to the planning and community development director or his/her designated representative with a copy to the engineer.

c. In the case of failing tests or poor workmanship, the planning and community development director or his/her designated representative may direct the lab engineer to perform additional sampling and testing.

d. The following is the minimum sampling and testing frequency:

1. Cross drain backfill: Minimum of one density test per pipe or box culvert location.

2. Storm drain backfill: Minimum of one density test per 500 lineal feet of pipe or portion thereof when the storm drain is located in the street or under the curb and gutter.

3. Embankment: Minimum of one density test per layer per 500 lineal feet of roadway or portion thereof.

4. Subgrade: Minimum of one density test per 500 feet of roadway with a minimum of three density tests per project, and one sieve analysis, LL and PI per project for subgrade soil classification.

5. Base coarse: Minimum of one density test and one depth measurement (depth sounding) per 500 lineal feet of roadway, with a minimum of three density tests and three depth measurements per project. Also, there will be a minimum of one gradation test and one PI test per project.

6. Asphalt stabilized base (black base), ACHM binder, and ACHM surface courses: For each material, a minimum of one density test and one depth measurement per 500 lineal fee of roadway, with a minimum of three density tests and three depth measurements per project.

7. Structural concrete for drainage structures: A minimum of one set of three concrete cylinders per 50 cubic yards of concrete or portion thereof. One cylinder will be broken at seven days and the other two will be broken at 28 days.

8. Structural concrete for curb and gutter: A minimum of one set of three concrete cylinders per 1,000 lineal feet of curb and gutter or portion thereof. One cylinder will be broken at seven days and the other two will be broken at 28 days.

9. Concrete pavement: A minimum of one set of three concrete cylinders per 500 lineal feet of pavement or portion thereof, with a minimum of one set per project. The set shall be broken in seven and 28 days as described above. Also, one core and depth measurement per 500 lineal feet of complete pavement with a minimum of one per project.
